To aZZ whom t mag/*concern Be it known that I, HERBERT L. Gr. MOORE,

a citizen of the United States, residing at` Richmond Hill, in thecounty of Queens, State of New York, have invented an Improvement inGrease-Proof 'Paper Vessels, of which the following is a specification.

My invention relates to a sealed paper vessel designed for holding oilsand greasy sub stances, andits object, is to render the same proofagainst leakage of the most penetrating of such substances, and with.this robject,A view I provide a cylindrical body provided with a bottomand cover eaclrpart being formed of a piece of paper of the desiredthickness, cut out of the proper shape and each covered on both sideswith a sheet of grease proof paper caused to adhere to the straw orother paper by shellac or other suitable adhesive material.`

I am aware that paper/vessels have heretofore been constructed of astrip of paper wound upon itself with layers of paraffin paperinterposing, and also that vessels of paper have 'been made with alining of parchment or waterproof paper, and for this reason myinvention is limited to the details of construction hereinafter moreparticularly described, its essential feature being the production of avessel of this character wherein the cut edge -of the interior seam orlapped portion of the body and also Vwhich is preferably cylindrical.and which the edges of the cover and bottom of the vessel are protectedagainst contact with the contents of the vessel which would otherwiseooze through the straw paper and injurefthe appearance of the vessel aswell asy dry out the contents.

In the accompanying drawing, in which like reference characters indicatelike parts throughout the several views;.Figure l is a vertical sectionillustrative of a vessel constructed according to .my invention, butvshowing the parts each in one thickness to accommodate space on thedrawing. Fig. 2 is a sectional plan in enlarged size of a p0rtion of thebody part taken at a point indicated by the broken line a: Fig. l toillustrate the folds. Fig. 3- is a sectional view also in enlarged sizeof the upper left-hand Vportion of a vessel constructed according to Amyinvention. Fig. 4 is, a similar View of the lower right hand portion.

Application led May 23, 1912. Serial No. 699,097.

proof paper Zi, c, is caused to adhere to the .paper parts'a, by anysuitable adhesive material, preferably shellac. At a predetei mineddistance from the upper edge of the body portion, an annular groove 4 isformed in the inner surface of the vessel, while the upper edge of thebody portion is doubled inwardly all around the vessel so that the edgeof this doubled-in portion extends only to the upper edge of the annulargroove 4.

The cover 3, has its edge folded upwardly upon itself, which folded-overportion is caused t-o closely adhere to the top surface of the cover byany suit-able adhesive ma terial. The cover 3 is of a shapecorresponding with the shape of the upper part of the vessel and is of asize adapted to be forced into the annular groove i, so that it will fitsnugly therein, and so thatI the folded edge of the cover extends evenwith or slightly beyond the edge of t-he doubledin portion of the upperedge of the body, which comes in close contact all around the vesselwith the upper surface of the fold of the cover, as illustrated in Figs.l and 3.

The edgeV of t-he lap in the body portion interior of the vessel, Ipreferably fold over upon itself as shown at d, Fig. 2, and secure it byany suitable adhesive material, preferably shellac.

At 'a suitable distance from the bottom of t-he body portion an annulargroove 5 is formed similar to the groove et, in the upper portion, andat a predetermined dista-nce below this groove 5, the body portion isfolded inwardly and upwardly with its eX- treme edge bent at rightangles to such upwardly folded portion, so that such right angled edgee, is on a line with and parallel to the lower edge of the annulargroove 5 all around.

The bottom 2 has its edge folded over downwardly upon itself, whichfolded over portion is caused to closely adhere to the under surface ofthe bot-tom by any suitable adhesive material. The bott-om 2 is of ashape' corresponding with the shape of the lowerl part of the vessel andis of a size adapt/ed to be forced into the annular groove 5, so that itWill lit snugly therein, while the folded over edge contacts with theupperV kbeen thus positively sealed, the vessel is ready for filling,and having received its contents, the cover 3 isY pressed into theannular groove 4 when the top of the cover is sealed in a similar mannerto the bottoni, and in addition to such-sealing, the

jentire exterior of the vessel may be coated with the substance known asWater-glass which gives a finished appearance to the same.

It Will be readily seen that in a vessel, constructed according to myinvention the body of straw paper ,and all the cut edges of the severalparts are positively protected from contactl with the/contents of theves-` sel, and it is absolutely .impossible for. the most "penetratingsubstances to leak or ooze through the vessel at any point.

The parts a may be formed board. or papier-mch. I claim as my invention:

A vessel for holding oily substances, hav: ing a body portion, a coverand a bottom each composedv of a body of paper with a covering on bothsides of a piece of grease-proof paper, the body portion having its endsoverlapped and pasted together,

of straw ,the inner lap having its edge folded over upon itself andagainst the outer fold, and secured in such position by adhesivematerial, said cover and bot-tom being so formed that When joined tothe' body portion their edges arefree from contact with the con' tentsof thevessel and are protected therefrom by said grease-proof papercovering..
